I've been a subscriber of satellite radio for a number of years now but have recently found it to be not worthy of keeping. The main culprit? The free to paid subscription streaming music services that are available online and through virtually all smartphones and tablets on the market.
The big advantage I see with going the an online music subscription route is cost and portability. The cost for a "premium package" usually includes unlimited commercial free streaming of music on your various devices. Some services even offer the ability to download the songs on your various devices so you can listen to them while you are off-line, like when on an airplane.
Many of these music services offer playlist creation and the ability to purchase songs via your respective phone/tablet provider's music store.
Now with satellite radio, you can stream music on portables devices for an additonal monthly fee which when added to the yearly fee will put you over by about $20 a year if you are able to secure their best renewal deal or initial subscrption package. In addition you also need to have an active cellualar or WiFi connection in order to listen to your programming.
This puts satellite radio at a disadvantage as you are limited or out of luck if you have poor or no connection option. Additionally, not all of the channels are commerical free. On certain channels you will still get ads played throughout the day, so the notion that it's commerical free is not entirely true.
So come renewal time in September, I won't be renewing my subscription to satellite radio, and instead use one of the paid streaming services.
